To simplify the algebraic expression 3x[(2x6-5) + (8\4)] -1, we follow the order of operations and get 26 as the final simplified expression.
The student is asked to simplify an algebraic expression. We proceed step-by-step, following the order of operations which is parentheses, exponents, multiplication/division (left to right), and addition/subtraction (left to right).
Our expression is 3x[(2x6-5) + (8 /4)] -1. We start by performing calculations within the parentheses:
2x6 = 12
12-5 = 7
8 /4 = 2
Add the results in the parentheses:
7 + 2 = 9
Now multiply by 3:
3 x 9 = 27
Finally, subtract 1:
27x - 1 = 26
The simplified expression is 26.
The simplified expression is 27 x − 1 . We simplified the original expression by following the order of operations, ensuring to handle calculations inside the parentheses first. Multiplication was applied next, leading to the final result after subtraction.
